Those must be made by a different manufacturer than the old ones because the flex heads were $79 at regular price a few years ago compared to what looks like $19.88 now. The old ones were made in Taiwan. Are these China?
I have the Metric and SAE of the older Taiwan version and they're actually very smooth wrenches with a 60 tooth gear mechanism. If these are 60 tooth Taiwan made I'd call that sale price a steal.
